It was only really there as a sentinel when instructions had to have precisely

that is sized.

Otherwise everything that needs to work out what size they are has to keep a
DataLayout handy, which is a bit silly and very annoying.

When coming from an IR label type, we set a 0 NumElements, but not
when constructing an LLT using unsized(), causing comparisons to fail.
Pick one variant and fix the other.
